2 week binge nightmare

Im 5'6 and was 132 lbs. but got down to 121lbs. 2 months. I was shooting for 117, but one day accidents u binged on 3000+ calories and from then on kept binging like that for 2 weeks. Now my loose jeans are snug and my once flat stomach looks 9 months pregnant. Even my thigh gap is almost nonexistent. I'm too scared to weigh myself but probably am at an insane weight. I think I binged because I was restricting for those two months to only 300-700 calories a day. Plus I've recently have stopped purging. Is it possible I gained all my weight back plus more? Is it possible it can mostly be water weight? I'm so scarred I gained like 10-20 lbs of pure fat. I just want to cry. Please help.
